1 Claim. c1. 189--75) This invention relates to window casings, and more particularly has reference to a window casing that is especially adapted for use with storm sashes.

One important object of the present invention is to provide window casings that can be readily fabricated in assemblies for double hung windows, as well as in assemblies usable to advantage in single units.

Another object is to provide a window casing which is particularly designed to permit its ready installation in a very short time, and without the requirement of special skills, thus permitting a householder to install the easings in his home without calling in skilled help.

Another object is to provide a casing as designed which will be particularly adapted for manufacture from readily fabricated sheet metal material of non-corrosive characteristics, thus not only to permit its construction at a relatively low cost, but to eliminate maintenance or at least reduce maintenance to a minimum.

A further object of importance is to provide a window casing of the type referred to, particularly designed to eliminate the use of nails in installing the same.

Yet another object is to provide a window casing which will be weather-resistant, and will have built-in rubber seals, thus to reduce to a minimum heat loss through the window.

Another object is to provide a window casing and associated window sashes, so designed as to permit removal of the sashes whenever desired without use of tools, thus to allow for opening of the window through its entire area if desired, and thus also to allow for removal of the sashes for cleaning purposes.

Summarized briefly, the window constituting the present invention includes a casing comprised of a pair of The sections each include a sash frame, and the respective sash frames are adapted to be separably interlocked by cooperating pinand-slot means provided upon the same, in an overlapping relation within a window casing opening of a building structure. Rigid with and surrounding the respective sash frames are casing frames, one overlying the interior wall of the structure in which the casing is mounted and the other overlying the exterior wall of said structure, with said casing frames extending about the window opening. The casing frames are formed with sill members, so as to cause the entire assembly to constitute a unitary structure when mounted, having the usual sill, stool, side Also provided as a part of the casing are stops or guideways for the respective sashes, and included in the invention are sashes so de- 7 signed in respect to the casings as to be removably mounted in the same, the sashes being of the double hung type and being bodily removable from the casing without requirement of special tools. Included in the construction are built-in weather strip means, sealing means to prevent vibration and also prevent heat loss, sash-locking means, and a screen adapted, along with the sashes, to be removably mounted in the installed casing.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:

Figure 9 is an enlarged, detail sectional view of the 'sash lock of one of the window sashes, on line 9-9 of Figure 4.

Referring to the drawings in detail, the window constituting the present invention includes a casing, a construction of which is shown in Figures 1-3, said casing being used in association with double hung Window sashes, a storm sash and a screen sash shown in Figures 4-9.

Considering first the construction of the casing, this includes a pair of complementary or mating casing sections A, B. The casing section A may be appropriately termed an outer casing section, in that it faces exteriorly of the building wall, not shown, in which the window is mounted, while the casing section B constitutes an inner casing section facing interiorly of said wall.

Considering first the construction of the casing section A, this is formed throughout, with the exception of Weather stripping, seals, etc., of a sheet metal material, and includes a stool or outer sill member 10, of approximately C-shaped cross section (see Figure 2) having an inclined top wall, a vertical bight portion, and a bottom wall formed intermediate its outer and inner longitudinal edges with a downwardly offset rib 12 extending the full length of the sill member to provide a shoulder adapted to engage the bottom edge of the window opening of the wall in which the casing section is being mounted. Braces 14 are interposed between the top and bottom walls, and said braces are spaced longitudinally of the bottom wall.

That edge of the sill member 10 that engages against the wall of the building is faced with a rubber sealing strip 16 which, as will be presently made apparent, is extended continuously through the full periphery of the frame of the casing section A.

Seam welded, spot welded, or soldered to the end portions of the sill member 19, so as to provide an air tight joint, are upwardly projecting side-jambs 18, 20 bent of sheet metal to a channel shaped cross section as shown in Figure 3, and similarly connected between the upper ends of the side jambs is a header 22- also of channel shaped cross section (see Figure 2). The side jambs and header, at their outer sides or walls, are integrally formed with an inwardly directed, continuous flange 24, and the continuous rubber sealing strip 16 is extended through the full periphery of the casing section in overlying relation to said flange 24, said sealing strip being cemented or otherwise bonded to the metal of the casing section.

A sash frame of rectangular formation is integrally formed with. the inner walls of the side jambs, and ex-' 3 tends continuously through the full inner periphery of the casing section. The sash frame 28, at its opposite sides, is integrally formedwith projections extending the full height of the sash frame, and extending inwardly within the window opening.

By reason of this construction, it will be seen that when the casingsection is in position within the window opening, the sill, side jambs, and header will overlie the edge portions of the Window opening, abutting against the eX- terior surface of the building wall. The sealing strip 16, 26 will be forced tightly against the surface of building wall, thus to'pr'ovide a peripheral seal for the casing section A, designed to prevent the loss of heat through the window after installation is completed, and further designed toeIiininate vibration of the installed window casing.

Secured to the side projections of the sash 28 are headed rivets 3%. As shown in Figure 2, these are disposed in vertical alignment, being spaced apart over the full height of the sash frame. The headed rivets are so formed as to dispose theflheads thereof inwardly from-the section A, substantially medially disposed between the upper and lower ends of said casing section.

Extending continuously about the sides and top of the .sash frame, and facing inwardly of the sash frame, is a channel member 32, providing a guide for a sash to be slidably mounted within the casing section A. The sides of the channel member would preferably be'faced with felt 'to provide a weather strip. Channeled spacers 34 are soldered or otherwise secured to the side portions of the sash frame 28 to space the channel member 32 outwardly from said side portions of the sash frame and to provide a stop for a top sash, which would be carried by the casing section A. A tubular member 36 extends from the lower end of the sash frame to a location approximately 7 opening. a

In the sash frame 56, there are formed'vertically spaced bayonet slots, and it will thus be seen that with the easing section A temporarily secured within the window opening, it is merely necessary to insert the casing section B from the other side of the wall, causing rivets 30 to enter the slots 53, after which the casing section B is dropped downwardly to cause the rivets to move into the inner ends of the slots 58. The sash frames 28 and 56 respectively comprise .parts of the casing sections A, B,

' adjacent areas of the sash frame, and said rivets, as will presently appear, constitute pins adapted to engage in so that they are part of the casing, and in no sense part .of the sashes.

associated sash, with a stop 62 being mounted in the guide 66, and a flange 64 being spaced from the stop 62 to} slidablyengage the sash. V

Freely. rotatable in the member 54 are safety locks 63, each having a head grooved to receive a screw driver bit,

, and a cross bar or latch element 65 (Figure 3)"on its medially between the upper and lower ends thereof, and

is embracedby the sides of theIchannel'member 32.

' Member 32 projects (Figure 3) slightly beyond member 36, to hold in place a screen sash to be described.

. Formed in the sides of the channel members, at locations spaced along the length thereof adjacent the stop 36, are recesses 38, the purpose of which is to receive locking stems or plungers carried by the associated sash, in a manner to be made presently apparent.

' To provide a weather strip extending along the botto I of the sash frame there is a strip 49 of the same material as the frame seam welded to the top wall of the sill member it in position to engage the lower rail' of the sash. i

If desired to assure a seal of maximum effectiveness between the casing sections A, B, there can be provided small, narrow, rubber sealing strips'42 extending along the edge of the weather strip 4%}, but this is not essential. Further, projecting inwardly from the sides of the sash frame, for the lower half of the height thereof, are flanges 44, cooperating with the channel or guide32 in providing a proper slidable mounting of the associated sash in the window casing section. Side rubber sealing strips 46 can be cemented tothe free longitudinal edges of the side projections of the sash frame, as shown in Figures 2 and 3, and a top rubber sealing strip 48 can also be employed if desired. These can, however, be omitted should 'it be found that theperipheral seals of the reglass is broken.

lower end engageable under the adjacent part of casing section A on rotation of the lock through degrees, thus to eliminate any tendency of the casing sections to come apartwhen the lower sashes are being raised.

'Referring now to Figures 49, there is here shown a set of sashes that can be employed to advantage in the window casing of Figures 13. These include a lower window sash 66, an upper window sash'68, a top storm sash 79, and a screen sash 72. As will be noted in Figure 5, two of the sashes 66 are employed, with that disposed adjacent screen 72 being a storm sash and that facing inwardly of the room being'the usual double hung lower window sash. The sashes 70, 72, together with the sash 66 that is disposed adjacent screen sash'72, are all' of a half screen is desirable ratherthan'a full screen, for

the purpose of allowing more light to permeate to the back of the room, where the light is needed most. The screen absorbs only 15 percent of the available daylight whereas a full screen can absorb as much as 5 0 percent.

In winter months, the lower storm sash is dropped to the position thereof'shown in Figure 5, and thus the window opening is provided with a double window composed of the two sashes 66 and the upper sashes 68, 70 with ventilation still being possible .whenever' necessary by raising the two lower sashes 66. The stops 36, 62, it will be understood, support the top sashes 68, 76.

Considering the construction of the sash 66 (see Figure 6) this has a bottom rail 74, as well as side and top rails, framing a glass 76 which is mounted in a peripheral, in wardly facing groove and is held in place by a suitable rubber molding which can be reused in the event the of the bottom rail, and a peripheral weather strip 86 is mounted in the window glass frame'of the sash 66. A

At .oppositesides of the sash 66, near the lower end thereof, there are provided latches or locks, the details of which are shown in Figure 9. Each includes a screw 82 constituting a handle, said screw projecting through a slot'84 formed in the sash frame, the slots communicat- Handles 78 are spaced longitudinally ing with a slot provided in the side wall of a cylindrical lock pin housing 86 having an axial bore 83 in which is shiftable a lock pin 95 one end of which has an enlargement 92 merging in turn into a locking head 9-71 slidable in a counterbore of the bore 88. A compression spring 96 is interposed between the enlargement 92 and the shoulder of bore 88 to normally urge the head 94 outwardly, but said head can be retracted by shifting the handle 82 to the other end of the block 84, viewing the same as in Figure 9. Ordinarily, when the sash 66 is lowered, the heads of the pins 9% will be engaged in the lowermost recesses 38. When the sash is raised, selected recesses are employed to receive the pins 90, to hold the sash in selected positions to which it is lifted.

The top sash 68 is similarly equipped with lock pins, to hold the same in selected positions to which it is slidably adjusted within the window casing, and the lower storm sash is also provided with the lock pin means illustrated and described. The upper storm sash 70 and the lower screen sash 72, however, are not equipped with the pin, since they are not movable within the window casmg.

Considering the construction of the sash 70, this has a glass mounted therein in the same manner as described with reference to sash 66. Formed upon the bottom rail 98 thereof is a depending, Weatherstripping flange 100 overlapping the upper rail 102 of the screen sash 72.

The screen sash 72 is provided with a flange 104 secured to the top rail thereof, said flange providing a handle for the purpose of pulling the screen sash out of the window casing whenever desired. Extending about the screen sash frame is a recess, and a wire mesh screen 1% has its edge portion engaged in said recess and held in the recess by a wire 108.

It will be seen that the construction is one which, in the first instance, permits the window casing to be installed in a minimum of time, and with maximum case. It is merely necessary that the casing section A be first temporarily held in the window opening, by means of two screws, one through each of the side openings 31. Then, the casing section B is inserted from the other side of the wall, with the headed rivets or pins 30 engaging in the slots 58. This completes the installation, with the rubber sealing strips, that extend peripherally of the respective casing sections, bearing tightly against the outer and inner surfaces of the building wall. Then, the sashes are merely inserted in the casing sections, and mounted in their respective tracks, the construction being one that provides a four track casing as will be apparent from Figure 5. The respective sashes can be removed with ease, to permit cleaning or ventilation through the entire area of the window, and further, the sash construction is such as to afford effective protection against the elements, as well as ease of replacement of any individual sash or any component part of a sash. The sashes are removed by springing the sash frames apart slightly at opposite sides thereof Whenever a sash is to be removed, sufficiently to be clear of the sides of the sash. The sashes are inserted in the same manner.

The entire device, with the exception of course of the necessary pins, rivets, screens, glasses, etc., can be made of sheet metal material, readily prefabricated in various sizes, and shapes, and obviously, said sheet metal material can be of a noncorrosive type, so as to reduce painting to a minimum. Still further, the casings can be removed from the wall whenever desired, so as to be usable at another location, in a difierent structure, should the occasion arise for said reuse.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claim.

What is claimed is:

A window casing comprising a pair of complementary casing sections engageable in a window opening, one of said sections constituting an outer section in the sense of facing exteriorly of a building wall and the other section constituting an inner section in the sense of facing interiorly of said wall, said sections being formed as rectangular, open-center structures each including as its component portions a sill member, side jambs, and a header, the sill member, side jambs, and header of each section being formed of sheet metal material and being of channeled formation, corresponding portions of the respective casing sections being in confronting relation with their channels opening toward each other to open in the direction of the adjacent surface of the building wall in engagement with said building wall, both sections having inner side walls on the sill members, side jambs, and headers, all of the inner side walls being of planiform formation and corresponding inner side walls of the sections slidably overlapping in face-to-face contact, the sill member, side jambs, and header of each section including a bight portion disposed in a vertical plane, the bight portions of the side jambs and header of each section being in the same plane and the bight portion of the sill member of each section being in a plane offset outwardly from the common plane of the side jambs and header of the same section, the side jambs and header of each section having flanges disposed outwardly from said inner side walls thereof in a common vertical plane for engaging the adjacent surface of the building wall area immediately surrounding said opening, the sill member of each section having an outer side wall formed with a downwardly offset rib one surface of which defines a shoulder coplanar with said flanges of the same section and adapted to engage the adjacent surface of the building wall along the bottom edge of the Window opening; a sealing strip extending continuously through the full periphery of at least the outer casing section as a facing for said surface of the rib and for said flanges of the side jambs and header of said one section, thus to provide a peripheral seal on said one casing section; and separable connections carried by the inner side walls of some at least of the confronting portions of the respective sections, interengaging in the slidably overlapped relationship of the inner side walls.
